GAS MAN软件辅助教学在麻醉住院医师培训中的初步应用评价

摘要

目的 评价麻醉住院医师培训中采用GAS MAN软件辅助教学对吸入麻醉药理论学习的作用.方法 将2010年至2012年进入华西医院麻醉科进行第一阶段二级学科培训的32名住院医师随机分为试验组(S组)和对照组(C组),各16人.两组在接受吸入麻醉药理论授课后进行理论测试1.之后S组采用GAS MAN软件开展计算机模拟教学(computer-based simulation,CBS),并自学参考书;C组仅自学参考书.结束后两组住院医师同时完成理论测试2;S组住院医师完成问卷.另纳入培训教师34名,参加GAS MAN课程后完成问卷.采用SPSS 16.0软件进行统计分析,住院医师年龄及理论测试得分以均数±标准差(x±s)表示,行Student's-t检验,性别比行x2检验.结果 S组和C组测试1成绩比较差异无统计学意义(P=0.64);S组测试2成绩(81.3±13.6)分,明显高于C组(61.3±15.4)分(P=0.001).100％ (16/16)的S组住院医师认为GAS MAN软件有利于吸入麻醉药理论学习;93.8％(15/16)的住院医师认为在自学时使用GASMAN模拟软件比单纯看书更易理解概念.97.1％(33/34)的教师认为采用GAS MAN进行的CBS有助于理论难点讲授;91.2％(31/34)的教师认为有助于住院医师提高学习效率.结论 采用GASMAN进行的CBS应用于麻醉住院医师培训,有助于提高学员理论测试成绩、学习兴趣和效率,被住院医师和培训教师认可,应作为常规课堂教学的有效辅助方法.%Objective To explore the effect of GAS MAN assisted instruction on theory learning of volatile anesthetics in anesthesiology residency training.Methods A total of 32 residents in the first stage of anesthesiology training were enrolled and randomly assigned to either study(S) or control (C) group.Theory-test l(Test-1) was conducted for all residents after the lecture-based learning (LBL).Next,reference book self-reading strategy was used in both groups while computer-based simulation(CBS) using GAS MAN was only developed in S group.Then,theory-test 2(Test-2)was conducted for residents in both groups and residents in S group completed the questionnaire smvey.In addition,thirty-four resident teachers observed the CBS courses and completed the questionnaire smvey.Results The mean scores of Test-1 did not differ significantly between the two groups(P=0.64).However,the mean Test-2 score of S group(81.3 ± 13.6) was significantly higher than that of C group(61.3 ± 15.4) (P=0.001).100％(16/16) residents believed that CBS was beneficial to the theoretical study of volatile anesthetics,93.8％(15/16) residents considered GAS MAN could help understand the concepts and improve efficiency during self-learning.97.1％ (33/34) and 91.2％ (31/34)resident teachers agreed that CBS was helpful for analyzing complex concepts and improving study effectiveness,respectively.Conclusions CBS using GAS MAN improves theory knowledge and study effectiveness for anesthesia residents.Both residents and resident teachers find GAS MAN highly ac ceptable.Therefore,GAS MAN has the potential to be the assistant teaching tool for LBL in anesthesiology residency-training program.
